[0053] Example 2

[0054] Based on Example 1, please refer to Figure 4-Figure 6 The formwork assembly 4 includes: a support drive ring 16, several groups of fixed blocks 15 are fixedly provided around the outer wall of the support drive ring 16, a central threaded column 18 is movably provided at the center of the support drive ring 16, several groups of through holes 12 are opened on the support pole 3, two groups of limit rods 40 are fixedly provided at the bottom of the support pole 3, and the two groups of limit rods 40 are movably provided in the central threaded column 18, the bottom of the support pole 3 is movably passed through the support plate 14 and abutted against the fixed block 15, and the top of the fixed block 15 is provided with several groups of blind holes for inserting the support pole 3.

[0055] Preferably, the drive motor 19 is fixedly mounted on the top of the support drive ring 16, and a pulley 20 is fixedly sleeved on the output shaft of the drive motor 19. Several groups of drive rods 24 are arranged in a ring shape on the top of the support drive ring 16, and the bottom of the drive rods 24 is rotatably connected to the drive ring 16. The outer wall of each group of drive rods 24 is fixedly sleeved with a drive gear 23 and a pulley 2 22 in sequence from top to bottom, and the pulley 22 is connected to the pulley 1 20 by a belt 21.

[0056] Preferably, the gear ring 25 is engaged with several groups of drive gears 23, and the outer wall of the inner ring of the gear ring 25 is provided with a drive thread, the central threaded column 18 moves through the center of the support drive ring 16, and the gear ring 25 is sleeved on the outer wall of the central threaded column 18 and connected to the central threaded column 18 through threads.

[0057] Preferably, in order to save costs, the hydraulic push rod 12 can also be supported by a telescopic rod that is locked with a pin or bolt used in common construction.

[0059] The working principle and beneficial effects of the above technical solution are as follows: while forming a support network with several groups of standard formworks 1 through the detachable connection components 2, the formwork components 4 are placed under the support network, the bottom of the support uprights 3 are passed through the through holes 12 and installed in the blind holes of the fixing blocks 15, and at the same time, the tops of the support uprights 3 are aligned with the detachable connection components 2, and the formwork components 4 are stabilized by unfolding the anti-roll stabilizing components 5 while the support plates 14 are lifted upwards until several groups of support uprights 3 tightly abut the detachable connection components 2 against the bottom of the standard formworks 1, and the driving is started. The motor 19 drives the pulley 1 20 to rotate, and the pulley 1 20 drives several groups of pulley 2s 22 to rotate through the belt 21. At this time, the driving rod 24 drives several groups of driving gears 23 to rotate while driving the gear ring 25 to rotate. Since the inner ring wall of the driving gear ring 25 is provided with a driving thread and the limiting rod 40 limits the central threaded column 18, the central threaded column 18 will move downward until it contacts the ground or the top plate below while the driving gear ring 25 rotates, thereby supporting the top plate formed by multiple standard templates 1.

[0060] Example 3

[0061] Based on any one of Examples 1-2, please refer to Figure 7-10The anti-roll stabilization assembly 5 includes: a triangular base 26, one end of the diagonal support rod 17 is rotatably connected to the support drive ring 16, the second fixed block 42 is fixedly connected to the diagonal support rod 17, the fixed end of the hydraulic support rod 41 is rotatably connected to the support drive ring 16, the movable end of the hydraulic support rod 41 is rotatably connected to the second fixed block 42, the other end of the diagonal support rod 17 is installed at the center of the triangular base 26 through a universal joint 33, a plurality of groups of guide grooves 28 are provided on the triangular base 26, a rack 27 is slidingly provided in the guide groove 28, one end of the second connecting rod 30 is rotatably connected to the rack 27, the other end of the second connecting rod 30 is rotatably connected to the H-shaped connecting piece 32, a plurality of groups of guide grooves 231 are provided on the outer wall of the diagonal support rod 17, and the H-shaped connecting piece 3 One end away from the second connecting rod 30 is movably arranged in the second guide groove 31. The support mounting member 29 is fixedly arranged on the top of the triangular base 26. Two sets of driving rods 34 are rotatably mounted on the horizontal section of the support mounting member 29. The outer wall of the driving rod 34 is provided with an engaging tooth groove 35. The driving rod 34 engages with the rack 27 through the engaging tooth groove 35. A driving screw 36 is fixedly arranged at the bottom of the driving rod 34. A tapered internal threaded sleeve 39 is sleeved on the outer wall of the driving screw 36. The driving screw 36 and the tapered internal threaded sleeve 39 are connected by threads. A limiting slide groove 38 is formed on the outer wall of the tapered internal threaded sleeve 39. A limiting plate 37 is fixedly arranged at the bottom of the triangular base 26, and one end of the limiting plate 37 extends into the limiting slide groove 38.

[0062] The working principle and beneficial effects of the above technical solution are as follows: when in use, by controlling the hydraulic support rod 41 to open several groups of diagonal support rods 17, the entire formwork assembly 4 is lifted so that the top of the support rod 3 can be inserted into the blind hole at the bottom of the stabilizing ring 6 and the entire top plate is lifted, and the triangular base 26 can play a supporting role. At this time, the central threaded column 18 will have a certain gap with the ground. After the central threaded column 18 is controlled to descend by the method in Example 2, the entire formwork system is supported. When an unexpected situation occurs, the diagonal support rod 17 deviates to one side or the support rod 3 and the formwork assembly 4 tilt to one side as a whole. The diagonal support rod 17 on this side will push the H-shaped connecting piece 32 to move along the second guide groove 31, thereby pushing the rack 27 to slide along the first guide groove 28 through the second connecting rod 30, and then the rack 27 drives the two sets of drive rods 34 to rotate. Since the two sets of drive screws 36 at the bottom of the two sets of drive rods 34 have opposite thread rotation directions, no matter which side the diagonal support rod 17 tilts, one of the two sets of tapered internal threaded sleeves 39 will rise and the other set will fall. The bottom of the descending tapered internal threaded sleeve 39 is a tapered structure, so that it can penetrate into the ground or increase the friction between the top plate below, preventing further aggravation of the tilt, thereby greatly improving safety.

[0063] Example 4

[0064] Based on any one of Examples 1-4, please refer to Figures 1-11 , also provides a steel frame formwork early dismantling formwork construction method for constructing a steel frame formwork early dismantling formwork system as described above, the construction method comprising:

[0065] S1: Install the corresponding detachable connection components 2 at the bottom of each set of standard templates 1, and connect the adjacent detachable connection components 2;

[0066] S2: After placing the formwork assembly 4 at the bottom of the supporting pole 3, first pass the bottom of the supporting pole 3 through the through hole 12 and then insert it into the blind hole at the top of the fixing block 15, then unfold the anti-roll stabilization assembly 5 and insert the top of the supporting pole 3 into the center of the detachable connecting assembly 2.

[0067] S3: Start the driving motor 19 to drive the central threaded column 18 to move downward and drill into the ground or the top plate below to support the whole;

[0068] S4: During disassembly, start the drive motor 19 to reverse and retract the central threaded column 18, then rotate the diagonal support rod 17 of the anti-roll stabilization assembly 5 so that the formwork assembly 4 is lowered as a whole to provide avoidance space for the removal of the support column 3, and then remove the detachable connection assembly 2 at the bottom of the standard formwork 1, and then pull the support column 3 out of the support plate 14.

[0069] The working principle and beneficial effects of the above technical solution are as follows: the formwork system can be installed through Examples 1, 2 and 3. During disassembly, it is only necessary to reverse the driving motor 19 to retract the central threaded column 18, and then control the hydraulic support rod 41 to move several groups of diagonal support rods 17 in the horizontal direction, thereby making way for the formwork assembly 4 to move downward as a whole. At this time, the support uprights 3 will be separated from the stabilizing ring 6, thereby facilitating the removal of the easy-to-disassemble connection assembly 2. Subsequently, the support uprights 3 can be pulled out of the formwork assembly 4, or the formwork assembly 4 with the support uprights 3 can be moved as a whole to the bottom of the next standard formwork 1 that needs to be supported. The installation can be completed by repeating the steps of Examples 2 and 3.

[0070] Among them, such as Figure 12 as well as Figure 13 As shown in the figure, the number and support method of the supporting poles 3 can be changed according to the number and position of the standard templates 1.
